Measure jaggery, add it to a pan, add water and mix it well.
Heat it up for 2 mins,let jaggery dissolve. Strain to remove impurities.
Remove the nel (the husk) from the pori and clean it, set aside.
Add the strained jaggery syrup to the pan and heat it up another time.
Then add cardamom powder and keep cooking in low flame. Keep a separate plate ready filled with little water. Take a drop of jaggery syrup and put it in water, it should stand firm. However, it should not dissolve.
First it will form soft loose ball then forms a firm hard ball. It should not be loose (soft ball) when you roll it with your fingers. This is the consistency we need. So when this consistency is reached, add cardamom powder and ghee.
Now mix well, so that pori gets completely coated with the syrup. I added in 2 batches. Lastly, mix well so that the syrup coats the pori evenly.
After that, grease your palms with ghee or oil, roll them into tight balls taking care not to break the pori. Similarly repeat to finish. Enjoy Nel Pori Urundai!
